Three-loop beta-functions and anomalous dimensions in the Standard Model
arXiv:1309.1643 · doi:10.1088/1742-6596/523/1/012045
Abstract
In this talk the methods and computer tools which were used in our recent calculation of the three-loop Standard Model renormalization group coefficients are discussed. A brief review of the techniques based on special features of dimensional regularization and minimal subtraction schemes is given. Our treatment of gamma5 is presented in some details. In addition, for a reasonable set of initial parameters the numerical estimates of the obtained three-loop contributions are presented.
